3 Claims. This invention relates to shingles, and more particularly to shingles of the substantially rigid type formed of asbestos-cement or like mate: rial.

Among the objects of the invention are to proproofing substance, and faced with mineral particles. The latter are made from a continuous web of a prepared roofing material which is cuteither longitudinally or transversely, generally longitudinally, to form shingles of the desired shape. Asbestos-cement shingles, however, are generally cut from individual square blanks or sheets of the material.

So far as I am aware, no commercially satisfactory asbestos shingle had been devised, prior to my present invention, which can be cut without waste from a square sheet, and has both vertical and horizontal self-aligning features.

Other objects and advantages of the invention will appear to those skilled in the art from the following description thereof, reference being had to the accompanying drawing in which:

Figure 1 is a face View of a shingle embodying the invention;

Fig. 2 is a plan view showing how the shingles are out without waste from a rectangular blank;

Fig. 3 is a plan view of a portion of a roof covering formed of shingles of this type; and

Fig. 4 is a face view of a modification of the shingle.

In the form of the invention illustrated in Figs. 1 to 3, inclusive, the shingle has an oblong body portion l0 having a straight horizontal lower edge H and two straight vertical side edges l2 converging side edges I9 and 20 and a straight horizonta1 top edge 2| disposed in the same plane as the top edge ll of the extension I4 but twice as long. The oblique edges [8, l9 and 20 each form an angle of about 70 with the upper edge of the body portion.

In the particular shingle illustrated, which is designed to be laid with an exposure of about six inches, the height of the extensions l4 and I5, measured vertically, is about three-quarters of the height of the body portion l0, similarly measured. This proportion is merely illustrative and may be varied depending upon the desired extent of exposure of the shingle.

The upper edge portion 22 of the body, between the side edge l3 and the extension I5, is of the same length as the top edge ll of extension 14, while the edge portion 23, between the I will be seen on reference to Fig. 3 of the drawing which shows a portion of a laid roof. In laying, the edges 22 and 23 of an overlying shingle A register with the edges 2| and II, respectively, 1

of the extensions of an underlying shingle B, thus aligning the shingles vertically with the proper extent of overlap and exposure. The comers 25 and 26 at the base of the extension l5 of the overlying shingle A register with the upper corners 21 and 28, respectively, of the extensions of the underlying shingle B, and thereby align the shingles horizontally to break joint in thirds.

The modified shingle illustrated in Fig. 4 is substantially the same in form and proportion as the one previously described except that it has an irregular lower edge 29 designed to give a so-called thatch effect when .the shingles are laid. In this case a slight waste of'material occurs along two opposite edges of the rectangular blank in cutting the shingles from the blank.

Various modifications in the form and construction herein described may be made without departing from the scope of the invention as defined in the claims.

What I claim is:

1. A shingle adapted to be laid with like shingles in overlapp n courses having a predetermined horizontal and vertical relationship, said shingle comprising a body having two spaced abs of unequal area extending upwardly there- I :om, the base of the larger tab being of a width substantially equal to the distance that the adjacent upper corners of the two tabs are spaced from each other, and said base being spaced from the adjacent side edge of the body a distance substantially equal to one-half of the width oi the top edge of said tab, the tabs being of lesser height than the body portion.

2. A shingle adapted to be laid with like shingles in overlapping courses having a predetermined horizontal and vertical relationship, said shingle comprising a body having two spaced tabs of unequal area extending upwardly therefrom, the smaller tab having one vertical side edge coincident with the side edge of the body, a straight top edge, and an oblique side edge, the other tab having a straight top edge and two downwardly diverging oblique side edges, the base of the larger tab being of a width substantially equal to the distance that the adjacent upper corners of the two tabs are spaced from each other, and said base being spaced from the adjacent side edge of the body a distance substantially equal to one-half of the width of the top edge of said tab, the tabs being of lesser height than the body portion.

3. A covering of shingles each comprising a body having two spaced tabs of unequal area extending upwardly therefrom, the shingles of successive courses being laid with the comers of the bases of the larger tabs of the overlying shingles in registration with the adjacent upper corners of the two tabs of an underlying shingle, and with the upper'edge of the body of each overlying shingle in alignment with the top edges oi the tabs of the underlying shingles, the joints between the shingles of each course lying centrally on the larger tabs of the shingles of the next lower course.
